Question

due to overfarming a field, the soil has become unsuitable for growing crops and is now covered with weeds. even the worms, which would have been helpful in restoring the soil’s fertility, are gone. which interference most likely occurred?

a. human interference led to the decomposition of the materials in the field, making it more fertile.

b. human interference led to increased productivity of the field.

c. human interference led to a change in the ecological succession of the field.

Explanation:

The problem describes soil degradation from overfarming (human activity), resulting in unsuitable crop growth, weed cover, and loss of soil organisms (worms). Ecological succession refers to the process of change in an ecosystem's species structure over time. Overfarming disrupts the natural succession trajectory—instead of progressing to a fertile, crop-supporting state, the ecosystem shifts to a degraded state dominated by weeds, which matches the scenario. Options A and B are incorrect because they claim increased fertility/productivity, opposite to the described outcome.

Answer:

C. Human interference led to a change in the ecological succession of the field.
